but something uses readX/write() calls. If you aren't using any driver
existing driver but only newly written dedicated for that SOC
you could use raw_read/raw_writeX() instead. These type of functions
are always using native endianess.

als long as hardware presents memory used with readX/writeX is
seen as little endian independant from CPU endianess it's generic.
